Definition: The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.

Positive Example 1 -
Input: Context: 'Well maybe we can work something out between us.  Our food and water was in the bags they loss so I really need those.  Do you think you could make do with 1 food and some water?' 'I really need 2 foods. I can do with 1 water or if you are in a giving mood then maybe I can have 2 waters? 🙂' 'Looks like we both really need the food.  If you get 2 food I would need 1 food, 2 water and 3 firewood. '
Utterance: 'Since you will get all the fire would do you think I could have 2 foods and 2 waters. You would get 1 food, 1 water, and 3 firewood. 🙂 You seem like you are a great outdoor person that I would think you would be able to catch some fish to cook with the firewood. 🙂'
Output: Yes

Positive Example 2 -
Input: Context: 'Kindly understand our need as we are struggling with hunger now.'
Utterance: 'At the same from my side. We need foods because my child is hunger'
Output: No

Negative Example 1 -
Input: Context: 'I believe that we have the same priorities.  So we have a large family including children that need the food, but my wife also needs firewood due to poor circulation.  She is susceptible to frost bite and limb loss' 'Okay so how about one of us takes 2 of the food and 1 of the firewood, and the other takes 1 of the food and 2 of the firewood?' 'that sounds fair.  I will take 1 food, 2 firewood, and 2 water, thus giving you 2 food, 1 firewood, 1 water'
Utterance: 'Okay that works for me'
Output: Yes

Negative Example 2 -
Input: Context: 'my counter then is 2 water, 1 food, and 2 firewood for us and we are set 🙂' 'We're really going to need that extra firewood.  We'll need the heat source, but also for cooking.  It a big deal that I get the extra wood, I hope you will understand why I need it.' 'my people feel like they need 1 extra of something or else they will throw a fit ☹️'
Utterance: 'No fits!!  They're getting that extra water they really want.  I am sure they'll be OK with giving a group with kids a little extra firewood to make this camping trip awesome for them'
Output: No

Now complete the following example -
Input: Context: 'I totally understand that. And it's pretty important, lol ' 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂' 'I definitely need the food the most. I'm definitely not a "hunter", so if I were to run out, I'd be in pretty sad shape. I do need the firewood for both cooking, and keeping warm. It gets cold at night where we're going. How about youself?'
Utterance: 'Well since we were already given a few supplies before this deal, I was wondering if you could give me all 3 water, and I could give you all the firewood and 2 of the food packages. I only say all the water because we already have some and my medical condition sucks. lol I wish we could camp together! we seem to be a good match. lol! 🙂'
Output:
